fascia is distinct and striking (Mr. Stainton says, in answer to my 

 enquiry on this point, " Amongst my mundella is one which just shows 

 a ghost of the pale hinder fascia, but in all my other specimens the 

 absence of the fascia is a striking character ") ; it also wants the neat 

 clean look of mundella, owing to the presence and irregular distribu- 

 tion of so many dai"k scales. 



I propose to call this species portlandicella.

DESCEIPTION OP A NEPTICULA {AUROMARGINELLA) NEW TO 

 SCIENCE FROM NEAR WEYMOUTH. 



BT KELSON M. RICH AllD SON, B.A. 



On the 22nd of October, 1888, I collected some Nepticula larvae 

 mining in bramble leaves, and was much surprised to find that three 

 moths which made their appearance on November 24th and December 

 7th and 19th respectively of the same year, though somewhat resem- 

 bling aurella, had besides the usual golden fascia, a second one of the 

 same colour, situated on the hind margin of the fore-wing. I do not 

 remember tliat I bred any other imagines from this jampot of larva?, 

 but from other batches there emerged one of these peculiarly marked 

 specimens on February 12th, and seven during May, 1889. After this 

 I was more careful, and when I found any bramble Nepticula larva) I 

 kept those from different localities separate from each other. I have, 

 however, so far only bred one more specimen with the golden hind 

 margin on September 30th last. Of this specimen I know the exact 

 locality, which is situated near Weymouth, and it is not improbable 

 that all my twelve specimens came from the same place, as I have 

 been in the habit of occasionally collecting Nepticula larvae from the 

 bramble there. I am not aware that I have bred any from Portland. 



I mentioned this Nepticula to Mr. W. H. B. Fletcher, of Worthing, 

 when staying with him last May, but though he has bred more Nepti- 

 culce than most people, he said that he had never seen this form from 

 bramble. As I could not identify it with any known species, I sent 

 some to Mr. Stainton, asking him for his opinion on them, which he 

 kindly gave me in the following words : — " The Nepticula from the 

 bramble with a gold line on the hind margin is quite new to me. I 

 have seen many aurella, both British and Grermau, but I never saw 

 anything like these." He also added that he thought that with my 

 series I might safely describe the species as new.
